Why Choose a Tankless Water Heater Over Traditional Tanks?

A hot water heater exists to provide hot water when needed, but traditional water heaters miss the mark compared to tankless options. Traditionally, systems consist of a tank and heating element that kicks on and raises the water temperature when the water cools below a preset temperature. Simple enough, right?

However, the amount of hot water received at any given time depends on a couple of factors.

  • How large is the tank?
  • How many people are using hot water at a given time?

As we've all experienced, putting demand on a water heater with multiple showers, doing laundry on the hot cycle, or running the dishwasher at the same time can quicky use up the available hot water. Since traditional systems have to heat an entire, large tank of water, it takes a while to replenish the supply of hot water, leaving you with lukewarm water at best.

With a good tankless water heater, running out of hot water won't even cross your mind.

Your tankless water heater is designed to rapidly heat water as it is needed, saving you money by only using electricity to heat what's being used instead of continuously heating a full tank of water for no reason. This saves you money, while also preventing unnecessary wear and tear on the unit. On the contrary, because of the inevitable water cooling and reheating while no one is present, traditional water heaters are woefully inefficient. Not only does this waste energy, but it even results in a reduction of the unit's lifespan.

Rinnai tankless water heaters offer great value, benefits including compact, space-saving designs and high-tech options, and are the best option for residential or commercial needs. As the top choice among consumers and businesses, Rinnai provides reliability you can count on and by buying from Advanced Water Solutions, LLC, you can be assured our team will make sure every system is expertly installed and properly cared for with preventative maintenance.
